Best build for a character focused on killing as many people as possible?

[Dubious Pie]

What is a good 13th level build for a character that can kill as many people as possible?

[WarKitty]

Wizard, or at least one of the arcane classes. Are we talking "fireball-it-to-death" killer or "poison-the-town-well" killer?

[ex cathedra]

Wizard, indeed. They're kind of alright like that.
In before "Locate Cities" and subsequent Locate Cities argument?

[Dubious Pie]

I picture "poke holes in them with a rapier" kinda killing.

[Claudius Maximus]

More information would be nice.

How responsible do you need to be for the deaths to "count?" If you make and enough Wights, they can spawn and grow exponentially until they kill a stupid number of people.

What kind of timescale are we talking about? An immortal character can kill trillions over a long enough span of time.

In any case, there are a lot of spells that can level or smother entire cities. Blizzard and Control Winds come to mind. I believe you could cast both with the same character at 13th level.

I meant a melee character more about killing a bunch of weak monsters.

I meant a melee character more about killing a bunch of weak monsters.So low AC, low HP mooks, by melee.

So you want a Psychic Warrior (http://www.d20srd.org/srd/psionic/classes/psychicWarrior.htm) with Expansion (http://www.d20srd.org/srd/psionic/powers/expansion.htm), and either Great Cleave (http://www.d20srd.org/srd/feats.htm#greatCleave) or Whilrwind Attack (http://www.d20srd.org/srd/feats.htm#whirlwindAttack) and Exotic Weapon Proficiency (http://www.d20srd.org/srd/feats.htm#exoticWeaponProficiency) for a Spiked Chain (http://www.d20srd.org/srd/equipment/weapons.htm#chainSpiked).

Will do reasonably well at giving mooks some stabbity death.

In that case, you should probably look into loving the greatsword (http://www.giantitp.com/forums/showthread.php?t=127026), being a lion (http://www.giantitp.com/forums/showthread.php?t=103358), and you should probably read this (http://www.giantitp.com/forums/showthread.php?t=127026) for kicks. Also, Barbarians (http://brilliantgameologists.com/boards/index.php?topic=8753.0) and Hood (http://brilliantgameologists.com/boards/index.php?topic=7200.0).

Ah, well what you're going to want is a good protection against their attacks, so you can murderize them in safety. The best way to obtain this is with magic, I'm afraid, but I suppose good armor and some DR can suffice. Regeneration or Fast Healing would also be good.

Next you'll want a means to kill many creatures quickly. Great Cleave is nice, as is some form of Dervishey ability combined with a large number of attacks. I believe there's a ToB maneuver that lets you attack freely during a move. You can kill a great deal of mooks in a single turn with such a combination. Such methods are not entirely necessary, however, if you can simply survive in melee long enough.

[Greenish]

Trippy, reachy crusader sounds about right. You can end people who come close to you with AoO and then walk up to the ones further away and smash 'em with boosted strikes, while regaining hitpoints.

Also, you do not "slash holes" with a rapier.

[Biffoniacus_Furiou]

I'd go with a Water Orc (http://www.d20srd.org/srd/variant/races/elementalRacialVariants.htm#racesOfWater), Dragonborn of Bahamut (http://www.wizards.com/default.asp?x=dnd/iw/20060105b&page=1), Mineral Warrior (http://wizards.com/default.asp?x=dnd/ex/20031003e), having bought off the LA (http://www.d20srd.org/srd/variant/races/reducingLevelAdjustments.htm) at a cost of 3,000 XP. That way you'll be only 3,000 XP behind everyone else with a +0 LA, rather than constantly being an entire level behind. Go with the wings aspect of dragonborn, since you'd be gaining mineral warrior after dragonborn but prior to 6th level you'll still get a fly speed to go with your land, burrow, and swim speeds and keep all the mineral warrior qualities. Your total racial ability score adjustments would be Str +6, Dex -2, Con +8, Int -4, Wis -4, Cha -4, plus you'd get +3 natural armor and DR 8/Adamantine along with everything else both templates grant, and you'd only lose the orc light sensitivity. Note that dragonborn does not cause you to lose your base race's favored class, it grants fighter as an additional favored class along with whatever your base race already had.

For your final build go Wolf Totem Barbarian (http://www.d20srd.org/srd/variant/classes/variantCharacterClasses.htm#barbarianVariantTotemB arbarian) 2/ Warblade 4/ Frenzied Berserker 10/ Warblade 4, using the lion spiritual totem ACF from Complete Champion to trade your barbarian fast movement for pounce, along with the whirling frenzy (http://www.d20srd.org/srd/variant/classes/classFeatureVariants.htm#rageVariantWhirlingFrenzy ) variant for rage. You'll want two flaws (http://www.d20srd.org/srd/variant/buildingCharacters/characterFlaws.htm) to get enough feats, I'd go with shaky and murky-eyed or maybe vulnerable, and remember you get improved trip for free at barbarian 2. Your feats should be power attack, cleave, intimidating rage, knock-down (http://www.d20srd.org/srd/divine/divineAbilitiesFeats.htm#knockDown), destructive rage, righteous wrath, extra rage, great cleave, and extra rage again. Your stances should be hunter's sense and absolute steel stance. Maneuvers should be steel wind, sudden leap, wall of blades, battle leader's charge, and iron heart surge.

13th level WBL is 110,000 gp. I'd get +1 mithral breastplate with +1 brash armor spikes, a +1 animated heavy steel shield, armbands of might, mask of blood, healing belt with +strength added, cloak of the predator with +resistance to saves added, ring of protection, amulet of natural armor, etc. After all that you should still have enough to get a +5 equivalent weapon. It should be a piercing weapon so you can make dive attacks with it at double damage. Note that you can get a reach weapon and still threaten adjacent squares with your armor spikes. I'd go with a ranseur for lack of better options. Make it +1, valorous, wrathful healing, so it will deal double damage whenever you charge and you'll be healed for half of every hit you land with it.

So low AC, low HP mooks, by melee.

So you want a Psychic Warrior (http://www.d20srd.org/srd/psionic/classes/psychicWarrior.htm) with Expansion (http://www.d20srd.org/srd/psionic/powers/expansion.htm), and either Great Cleave (http://www.d20srd.org/srd/feats.htm#greatCleave) or Whilrwind Attack (http://www.d20srd.org/srd/feats.htm#whirlwindAttack) and Exotic Weapon Proficiency (http://www.d20srd.org/srd/feats.htm#exoticWeaponProficiency) for a Spiked Chain (http://www.d20srd.org/srd/equipment/weapons.htm#chainSpiked).

Will do reasonably well at giving mooks some stabbity death.

I second this, though a ToB class could also be a decent alternative.

Or you could, you know, go druid and be two meleers that summons more.

[cupkeyk]

I have always liked the image of a rogue master thrower who can honestly stand in a town square with demand their surrender or else he will kill everyone (commoners).

[Grumman]

I meant a melee character more about killing a bunch of weak monsters.
Light Cavalry Scout / Mounted Combat Ranger (or Ranger-variant Barbarian) Swift Hunter with the Lance of the Unending Charge? Carve a 25 foot wide corridor through your foes.

[Ormur]

Invisible cloudkill or fell-drain metamagic shenanigans on low level area effect damage spells are the first things that come to mind for killing many low HD victims at that level.

Edit: Sorry, missed the preference for melee.
